Wrapping Up
In this chapter we took a hard look at the mechanisms behind def. They’re remarkably transparent: def creates a var (a Clojure value) which is an association between another Clojure value (a symbol) and a third value. We also looked at dynamic vars—vars that let you swap in a new value while you evaluate an expression or six.
Armed with an understanding of def and vars, we’re now ready to look at namespaces, the mechanism Clojure uses to organize vars into related buckets.
